A terminal includes a connection unit, an acquisition unit, a memory, a detector, and a transmitting unit. The connection unit connects the terminal to a processing apparatus through a first communication channel for wireless communication using connection information. The acquisition unit acquires identification information of the processing apparatus. The memory stores the connection information for the first communication channel and the identification information such that the connection information is associated with the identification information. The detector detects that the connection to the processing apparatus through the first communication channel is cut off. The transmitting unit transmits, in a case where the detector detects that the connection to the processing apparatus is cut off, connection information used when the processing apparatus is connected to the terminal to the processing apparatus via a second communication channel using the connection information and the identification information stored in the memory.
